Subject [jira] [Commented] (FALCON-1754) JobCompletionService throws FalconException
Date Tue, 19 Jan 2016 04:59:39 GMT

    [ https://issues.apache.org/jira/browse/FALCON-1754?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15106245#comment-15106245
] 

Ajay Yadava commented on FALCON-1754:
-------------------------------------

Ok. However, the concern still remains. Someone is being tried to handle an event which they
can not handle and hence it shouldn't have reached to them. Will take a look at the flow and
come back on it.
